Electrokinetic techniques for removing heavy metals from municipal sludge technical level, but research still remain in the existing form and the pH value, the voltage gradient, additives and strengthen technical factors such as heavy metal heavy metal removal efficiency for deeper principle, the nature of the sludge concentration polarization process, heavy metal migration characteristics cathode region of high concentrations of heavy metals in sludge subsequent processing and operating costs and other issues are still in a blank state, these areas remains to be further research. 2.4 Solidification-Stabilization Method The heavy metals in sewage sludge solidification - stabilization is refers to the use of physical and chemical methods sludge and stabilizing inert material blending together, rely on inert material adsorption, curing effect such as make heavy metal into low solubility and low mobility of steady state and not easily by leaching, so as to achieve the purpose of eliminate
